: This paper outlines the basic spatial principles of level design in multi-player first-person shooters with special reference to Counterstrike, basing itself on experiment, analysis, and theoretical discussion In this manner, the paper addresses the following questions: What characterizes good level design in firstperson shooters? Which criteria are necessary in the level-design process in order to obtain quality? The thesis of the paper is that a consistent examination of a game’s gameplay, its agents, and spatial components is necessary for the development of a design method that would lead to ultimate level design. Setting off from a theoretical discussion of the terms gameplay and emergence, the paper starts by establishing the basic characteristics of multiplayer shooters. The concept of emergence leads to a distinction of the unique features of multi-play and teamplay, and concepts of gameplay helps us map out the basic spatial properties of the game environment and its stagi...
